흔히 이렇게 알고 있다

Transpiling object rest destructuring and object spread with @babel/preset-env preserves accessor descriptors like getters and copies inherited prototype properties onto the resulting object.

이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.

컨트랙트

• Transpiling object rest destructuring and object spread with @babel/preset-env evaluates getters into plain data properties, drops inherited prototype properties and non-enumerable properties, but preserves own enumerable Symbol keys.
• Transpiled class instance spread creates a plain Object, stripping prototype methods, prototype getters, and class prototype identity.
• Transpiled subclass field initialization uses [[Define]] semantics via Object.defineProperty, creating an own property without invoking matching base class setters.
• Transpiling with explicit target environments desugars rest and spread syntax into _objectWithoutProperties and _objectSpread helper functions while retaining standard evaluation order and semantics.
